LOT is lot number, EXP and 4 digits are expiration date.
EXP means Expiry date (Exp date). Generally the date marked on the product is: "Manufacturing date" abbreviation is MFG. "Expiry date" abbreviation is Exp. mfg date=manufacturing date: Manufacturing date;
exp date=expiry date Expiry date,expiry date .
Extended information:
EXP is called Exponential, and it has only one setting, which is applied to both ends and is symmetrical in both directions. It is symmetrical, but this parameter does not change the maximum travel of the servo.
It's function is to convert the original straight line relationship between the telemotor and the rudder into an exponential curve relationship, changing the sensitivity of the telemotor from the center point to the upper and lower 1/2 positions and the rudder from the 1/2 to the upper and lower tops.
The EXP function is usually combined with the D/R switch to switch between the different values of the parameter.
Description An error occurs if the ?number? parameter exceeds 709.782712893. The value of the constant ?e? is approximately 2.718282.
Note that the Exp? function completes the inverse of the ?Log? function and is sometimes referenced in antinomial form.
The following example utilizes the ?Exp? function to return a power of e:
Dim MyAngle,MyHSin ' Define the angle in radians.MyAngle = 1.3 ' Calculate the sine of the hyperbola.MyHSin = (Exp(MyAngle) - Exp(-1 * MyAngle)) / 2.
